Chevalier’s specimens from the Upper Oubangui represent a stunted con- 
dition with the divisions of the panicle much more spreading and rigid than 
usual. Mez describes the mature fruits of his P. mixtum as brown. 
46. P. paucinode, Stapf. Annual, tufted, 1-2 ft. high. Culms 
erect or geniculate-suberect, very slender, glabrous, 1-2-noded, 
simple or sometimes branched from the lowest node, branches 
similar to the main culm, flowering. Leaf-sheaths thin, somewhat 
tight or the lowest at length loosened, striate, glabrous, shorter than 
the internodes, sometimes tinged with purple ; ligule reduced to a 
narrow membranous ciliolate rim ; blades linear from an equally 
wide or somewhat attenuated base, tapering to a slender point, 
2-4 in. by 1-1 J lin., flat or convolute when dry, subflaccid, glabrous 
except for a small beard at the junction with the sheath, midrib and 
primary lateral nerves (2-3 on each side) slightly prominent below, 
very slender, hardly differentiated above, margins scaberulous. 
Panicles mostly in tiers of 2-3, shortly or the primary at length long- 
exserted from the uppermost sheaths of the culm and its branches, 
open and very loose, oblong, up to over 1 ft. long by 14-2 in., quite gla- 
brous, divided to the fourth degree, all divisions very slender to almost 
capillary, scaberulous except the bases of the primary, obliquely 
spreading ; primary branches mostly solitary and scattered, rarely 
pseudo verticillate, with minute motile cushions at the base, divided 
from 3-6 lin. from the base, or occasionally quite low down, the 
longest up to 2 J in. long, divisions distantly divided once or twice, 
6-2-spiculate or the upper simple ; pedicels 3-6 or occasionally 
9 lin. long, tips slightly thickened and minutely discoid. Spikelets 
to over 1 J lin. long, oblong, acutely acuminate, soon gaping, yellowish- 
green or tinged with purple. Glumes obliquely spreading but not 
divaricate, similar, thinly membranous, finely nerved ; lower 
obliquely ovate to ovate-lanceolate in profile, acuminate, usually 
with a fine mucro, without the latter about two-thirds the length of 
the spikelet, 3-nerved, lateral nerves faint, midnerve slightly scaberu- 
lous ; upper obliquely lanceolate-oblong, shortly acuminate, 
obscurely mucronulate, as long as the spikelet, 5-nerved, inner nerves 
prominent upwards. Lower floret ; valve very like the upper 
glume, but less acuminate and subacute ; valvule almost as long as 
the valve, oblong, subacuminate, flaps broad downwards ; anthers
